Peripheral nervous system consists of two divisions

Somatic and autonomic nervous system

What is afferent

Carries information to the central nervous system. (Sensory)

What is efferent

Carries information from central nervous system to other body parts (motor)

Both sympathetic and parasympathetic nerves are ?

Efferent and have opposite effects

In the sympathetic region where do neurons originate ?

In the thoracic and lumbar regions of the spinal cord

Where do neurons originate in the parasympathetic region?

In the cervical and sacral religions of the spinal cord

What are the three meninges in the central nervous system?

Dura mater, arachnoid membrane, and pia mater

Singer that sings "do it again"

What is the dura mater?

Hard mother, flexible but thick and tough, the outermost layer

What is the arachnoid membrane?

Web like appearance, soft middle layer

Pia mater

Pious mother, attached to the brain and spinal cord

What do the meninges cover ?

The brain and the spinal cord

What does the cerebrospinal fluid do?

Serves as a cushion to protect the brain

Protects what

Function of blood-brain barrier

A mechanism impedes the passage of many toxic substances from the blood into the brain

The spinal cord comprises two different areas

Gray matter and white matter



Gray matter: composed largely of cell bodies and Unmyelinated interneurons. (Inner)



White matter: composed largely of myelinated axons. (Outer)

Dorsal

Afferent and sensory

Ventral

efferent and motor

What are the 5 structures of the brain?

Myelencephalon


Metencephalon


Mesencephalon


Diencephalon


Telencephalon

What is myelencephalon?

Medulla. Composed of tracts carrying signals between the rest of the brain and body.



-Reticular formation





-FYIcomplex network of about 100 tiny nuclei hat occupies the central core of the brain stem.

What is the metencephalon

It has pons. Pons is one major division and the other is the cerebellum

What is the mesencephalon?

It has two divisions: tectum and the tegmentum

What is tectum?

Dorsal surface of the midbrain.


Visual(superior colliculi) and auditory reflexes (inferior colliculi)

What is the tegmentum?

Division of the mesencephalon ventral to the tectum.


The tegmentum contains three colorful structures of particular interest to biopsychologists

Periaqueductal gray


Substantia nigra


Red nucleus

What is the diencephalon composed of

The thalamus (sensory) and the hypo(below thalamus) thalamus (motivated behavior) such as eating sleeping.

What is the telecephalon?

Largest division of the human brain.


Voluntary movement


Sensory input


Complex cognitive processes such as learning speaking and problem solving

The cerebral hemispheres are covered by a layer of tissue called

Cerebral cortex (often referred to as the gray matter)

What is the Limbic system

Circuit of midline structures that circle the thalamus



Involved in the regulation of motivated behaviours

What is the hippocampus?

Important area of cortex that is not neocortex. Has only 3 major layers.

Amygdala

Plays a role in emotion


Structure anterior temporal lobe, just anterior of the hippocampus

The fornix

Major tract of the limbic system

Septum

Midline nucleus located at the anterior top of the comgulate cortex

Basal ganglia

Plays a role in the performance of voluntary motor responses

What is the longitudinal fissure

Separates right and left cerebral hemispheres

What are the four lobes of the cortex

Frontal


Parietal


Temporal


Occipital

Explain the Frontal lobe

Primary motor cortex


Broca's area (speech production)


Prefrontal cortex (personality and emotion)

Explain parietal lobe

Primary somatosensory cortex


Language processing


Visual spatial processing


Association processing

Explain temporal lobe

Primary auditory cortex


Language processing (wernicke's area)


Visual association cortex

Explain occipital lobe

Primary visual cortex


Process many aspects of vision
